Failure to read, understand and follow the instructions given in this
manual may result in serious personal injury, including amputation,
electrocution or death.
The owner of this machine/equipment is solely responsible for its
safe use. This responsibility includes but is not limited to proper
installation in a safe environment, personnel training and usage
authorization, proper inspection and maintenance, manual availability
and comprehension, application of safety devices, blade/cutter integ-

Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.

prevention measures.

Safety Instructions For Chain Hoists
Additional Safety Precautions for Chain Hoists
DO NOT attempt to lift a load
in excess of the rated load capacity.
DO NOT drag the load or lift it when it is
not directly under the chain hoist.
DO NOT wrap the lifting
chain around the load
to lift it—use a
separate chain.
DO NOT mishandle
the hoist assembly.
DO NOT allow the hook
to become twisted
around the chain.
DO NOT exceed the maximum lifting or lowering distance.
Read and understand this entire man-
ual before using this hoist. Serious
personal injury may occur if safety and
operational information is not under-
stood and followed. DO NOT risk your
safety by not reading!
Use this and other tools with caution
and respect. Always consider safety
first, as it applies to your individual
working conditions. No list of safety
guidelines can be complete for every
environment. Failure to follow guide-
lines could result in death, serious per-
sonal injury, or damage to equipment.

OPERATION
To operate the chain hoist:
1.
2.
Note: The hoist can be mounted on a
beam trolley if the capacity of the trolley
system is at least twice the maximum
load capacity of the hoist.
3.
Always connect the chain hoist lift-
ing hook to a separate lifting device
attached to the load, such as a strap, a
chain, or an eye bolt. DO NOT wrap the
hoist lifting chain and hook around the
load in any way. If you do, the dynamic
loads could exceed the capacity of the
hoist, causing it to fail and drop the
load. A falling load could cause death
or serious crushing injuries.
4.
5.
6.
7.
Note: The hoist has a built-in brak-
ing mechanism that will suspend the
load at the current position when you
release the lifting chain.
8.
9.
MAINTENANCE
Incorrect re-assembly of this chain
hoist could result in the failure of the
braking mechanism. Loads may not
stay suspended and could cause death
or serious crushing injuries if they fall.
All service or repair to the hoist MUST
be performed by a qualified hoist ser-
vice technician who is familiar with
this hoist.
If lubrication of any kind gets on the
parts of the braking mechanism, the
hoist could fail to suspend the load,
which could result in death, serious
personal injury, or property damage.
DO NOT allow any lubrication to get on
the parts of the braking mechanism!
